About the CMAS Math Grade 3 Exam
Colorado Measures of Academic Success (CMAS) Mathematics — Grade 3 is Colorado's grade-level Colorado Measures of Academic Success (CMAS) statewide summative assessment, developed by CDE with Colorado educators and Pearson against the Colorado Academic Standards. It is administered in the spring window (for 2026: April 6–24 per CDE FAQs) on Pearson TestNav. Official forms use mixed item types (selected-response, technology-enhanced, and for many content areas constructed-response tasks). OpenExamPrep free practice is an English-language four-option MCQ study adaptation aligned to CMAS reporting categories and grade-level CAS—not official secure items, not a full TE/CR simulation, and not a substitute for classroom instruction or the official assessment.
